Abstract
is a common uropathogenic bacterium that can cause major complications in patients with long-standing indwelling catheters or patients with urinary tract anomalies. In addition,
is a common cause of chronic osteomyelitis in Diabetic foot ulcer (DFU) patients. We isolated
from a Diabetic ulcer patient. We examined
levels of resistance against Nanosilver colloids, the commercial Nanosilver and silver containing bandages and commonly used antibiotics. We utilized next generation sequencing techniques (NGS), bioinformatics, phylogenetic analysis and pathogenomics in the characterization of the infectious pathogen.
was the first Nanosilver resistant isolate collected from a diabetic patient polyclonal infection.
showed high levels of resistance against Nanosilver colloids, Nanosilver chitosan composite and the commercially available Nanosilver and silver bandages. The
-SCDR1 genome size is 3,815,621 bp. with G + C content of 38.44%.
-SCDR1 genome contains a total of 3533 genes, 3414 coding DNA sequence genes, 11, 10, 18 rRNAs (5S, 16S, and 23S), and 76 tRNAs. Our isolate contains all the required pathogenicity and virulence factors to establish a successful infection.
SCDR1 isolate is a potential virulent pathogen that despite its original isolation site, the wound, can establish kidney infection and its associated complications.
contains several mechanisms for antibiotics and metals resistance, including, biofilm formation, swarming mobility, efflux systems, and enzymatic detoxification.
is the first reported spontaneous Nanosilver resistant bacterial strain.
possesses several mechanisms that may lead to the observed Nanosilver resistance.
